02 sensor harness help. Hi I have a 2000 Transam with QTP long tubes. I have a problem with my 02 sensors and need to start off by making sure they are plugged in right. My rear 02 sensors are deleted, but I have four possible locations in which to plug them in at. I think I screwed up somewhere, so I want to double check the plug in locations of the FRONT 02 sensors. Can someone please tell me specificly where the passenger and driver front 02 harness is located at? If this is not my problem I think the Bosche 13111's I bought are fautly. Please help, thank you.

Also, what V should a properly functioning 02 display? Will both banks display the same voltage? One is displaying roughly 0125 and the other one is around 0435 i think, maybe off a bit. I pulled the fuse for the 02's because right now it runs like utter ****. Something is wrong.

I had this same problem...When your able to find out which ones go where. You should delete the old wires so you have no problems next time. What codes are coming up after you scan it?

It doesn't seem to be throwing any new codes when I scan it. I went ahead and pulled my MAF fuse, she is running good now but will run much better when I pull them. I really need a wiring diagram or something, pictures would be great. PLEASE someone with a LT car post pictures of your 02's.
